Instead, it is because K and Cl react in a 1-to-1 molar ratio. A mole consists of 6.02 × 1023 irreducible "pieces" (atoms or molecules) of a substance. Every element's molar mass, or the mass of a single mole in grams is given in the periodic table of elements (see the ...
In chemistry, mass ratio, often called "percent composition by mass," is the proportion of a particular molecule that consists of each that molecule's constituent elements. For example, water consists of 11.1 percent hydrogen (H) and 88.9 percent oxygen (O), meaning that a 1,000-gram sample...
Molecular formulas describe the exact number and type of atoms present in a single molecule of a compound. The constituting elements of a compound are represented by their chemical symbols followed by numeric subscripts describing the number of atoms of each element present in the molecule. A molec...

The Products of a Reaction:The mass of the products in a reaction is determinable in two ways. One way is calculating the mass of the formulas on the product side and then adding them up. Another way is to calculate ...
The empirical formula of a compound is {eq}CH_2O {/eq}, and its molar mass is 60 g/mole. Calculate its molecular formula. Molecular Formula: In the problem, the empirical formula of the compound was provided. It is important to know that t...
Solubility describes the amount of a substance that can be dissolved in another substance. This measurement can range from nearly completely insoluble under any conditions, such as oil and water, to near infinitely soluble, such as ethanol and water. The

Answer to: A unit cell contains 4 atoms of copper at a density of 8.96 g/mL. The molar mass of copper is 63.55 g/mol. Calculate the volume of the...
Create a MATLAB function called P_{VDW.m} that solves the pressure using the van der Waals Equation of State (EOS). This EOS inputs temperature and molar volume and two parameters, a and b. The equation is P=RT/(V-b) - a/V^{2}. ...
